It has been the prosecution's case during the trial that Pistorius killed Reeva following a row.

But yesterday, Gerrie Nel also argued that even if the court accepts that Pistorius believed there was an intruder, he still "fired shots with intention to kill... the intention was to shoot a person in that bathroom".

He added: "The mere fact [that person] later turned out to be Reeva and not an intruder is of no consequence".

8:20 am

Oscar Pistorius has arrived for the day's hearing.

His father Henke is here again, having come to court for the first time in the five month trial yesterday.

Reeva's parents, June and Barry have also arrived.

8:38 am

Barry Roux has picked up where he left off yesterday, raising objections to a number of smaller details in the prosecution's closing speech.

The court is shown photographs of police at the crime scene, and Roux raises questions about position of fans in Pistorius' bedroom.

He says police showed "no respect" for the crime scene.

8:45 am

Roux says they are not alleging a conspiracy by the police, but that objects were moved "inadvertently".

He goes on to raise questions about the differing accounts of which police officers were on the scene.

He asks why the prosecution did not call Investigating Officer Hilton Botha as a witness.

8:53 am

Roux addresses what the prosecution referred to as Pistorius' "perception" of an intruder.

But the defence barrister says the athlete has repeatedly maintained this version of events.

He argues that the trial "should have started" at a charge of culpable homicide.

8:57 am

Roux touches on the prosecution's argument that the bullet holes in the door are in a "good grouping". Gerrie Nel yesterday suggested this showed "aiming", and not "wild" shots.

But Roux says while he is not a good shot: "If you put me two metres from a door and fire four shots, I'm pretty sure I can get a good grouping."

He says the court should not get sidetracked by that issue.

9:01 am

Roux says Pistorius fired the shots from the bathroom door, suggesting he was scared.

He moves on to talk about Nel's argument, based on WhatsApp messages, that Reeva was unhappy in the relationship in the weeks before her death.

He says every single WhatsApp message after February 7 shows they had made up - they were "lovey" with kisses.

9:06 am

Nel yesterday asked why Pistorius did not ask the security guard for help of call the police after the shooting.

But Roux says he called 911, rather than the police, "which is far more significant because he wanted to save her life".

Roux says the defence agree Pistorius did arm himself, went to the toilet, and saw it might be necessary to fire that shot. He was "anxious, he was fearful", he was vulnerable on his stumps.

He says the insecurities of a disabled person should be considered a "slow burn" over the years, and these events should not be considered in isolation.

9:11 am

Roux says Pistorius is trained as an athlete to react to sound, and he stood there [outside the bathroom door] with his finger ready to react if necessary, then - bang! Roux bangs his hand down on the table

"When he heard that sound, in his vulnerable state, with regard to the slow burn... anxiety... reaction to sound as an athlete."

He says Pistorius' reactions can be interpreted as reflexive.

"That is your primal instinct."

If the court agrees, then Pistorius lacked criminal capacity.

9:16 am

Roux says Pistorius grew up knowing: "You're a little boy without legs, you experience daily that you cannot run away. 'I don't have a flight response'.

"Over time you get an exaggerated fight response. That's why you don't go. That's the slow burn.

"That constant reminder, 'I do not have legs, I cannot run away, I am not the same'."

"The moment you're confronted with danger, or perceived danger, it comes to the fore. You are compromised because of the slow burn, because of the anxiety, because of your real position."

9:34 am

Roux addresses the Nel's assertion that Pistorius was "aggressive" in the witness box.

He says this was because he was being accused of putting on his prosthetic legs before shooting. The state later changed their position on this, he says.

9:37 am

Roux is now dealing with the firearms charges that Pistorius also faces.

He questions the evidence given by Pistorius' friend Darren Fresco, pointing out he had given given indemnity and so had an "agenda".

He also challenges the evidence given by the athlete's ex Sam Taylor, who accused him of cheating on her with Reeva.

He says she "had a motive".

9:43 am

He goes back to the murder charge, and sets out the "common cause facts".

He says there were four shots fired, fire holes in the door, and four empty shells.

Subsequent to the shots, the door was damaged by a cricket bat.

After the shots, Reeva could not have screamed.

He says there were two sets of sounds. The cricket bat striking the door is not as loud as the gunshots.

9:52 am

Roux is using phone records to back up the timeline of events provided by Pistorius.

"We know the first shots were about 3.12am. We know the 'help help help' shout about two minutes later."

The defence says this was Pistorius after realising what he had done.

9:58 am

Roux talks about the evidence of security guard Pieter Baba, who said he went past Pistorius' house at around 2am - when he and Reeva are alleged to have been arguing.

But Baba said everything was normal.

"This is fatal for the state," says Roux.
